ACETYLENE-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 716,153, dated December 16, 1902.

Application filed January 3,1902. Serial No 88,309. (No model.)

- To all whom it may concern:

' Be it knownthat I, SEEN P. WATT, residing at Morgan Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Acetylene-Gas Burners,of which the following is a specification.

My invention relates to acetylene-gas burners; and its object is to provide a simpleand efficient device of this character, one capable of overcoming certain disadvantages of such burners, chiefly the disadvantages of clogging with the tar or carbon formed therein.

In the drawings, Figurelis a side elevation of my burner. Fig. 2 is a'central vertical section thereof; Fig. 3, an elevation of the removable top portion or section of the burner; Fig. 4. an elevation of the lower section thereof; Fig. 5, a plan view'of the upper section, and Fig. 6 a plan view of the lower section. 1

The burner is made in two parts or sections 1. and 2, removable from each other, as illustrated by Figs. 3 and 4. The upper section 1 has the enlarged cylindrical portion 3 and the reduced cylindrical portion 4, whereby two bores of different diameters are provided. The burner-tip 5, which is here shown as a separate piece and with a conical recess on its under side, Figs. 2 and 5, is secured to the reduced cylindrical portion 4: in any suitable manner. Such upper section is preferably milled on a portion of its edge, so that it may be better grasped when the same is being removed from the lower section. The extreme upper end of the upper section is first formed straight, and after the burner-tip 5 has been inserted such upper end is rolled over upon it in the well-known way.

The lower section 2 is of cylindrical form, having a top marginal flange 6, which is itself upwardly flanged or provided with a rim 7. Such lower section may be screw-threaded or providedwith other suitable means of attachment to a supply-pipe, and has a central bore or minute gas-passage 8 arranged in axial alinement with the tip-orifice 9. The flange 6 is provided with one or more holes 10 for the passage of oil, which becomes mixedwith the acetylene gas. The flange 6 of the lower section is exactly of the same diameter as the inside diameter of the larger bore of the upper section and is received thereby. For the purpose of retaining the lowersection normally in place I take advantage of the spring tension or resiliency of the larger or shell portion 3 of the upper section, providing it in the present instance preferably with a plurality of'indentations 11, which project inwardly slightly and act as spring-points, Fig. 2. The lower section is bodily insertible and removable from the upper section, and when inserted the flange 6 of the lower section striking against the spring-points forces them outward to admit and then snap back underneath such flange just'after it has passed to proper position, as Shown in Fig. 2.

When the two sections of the burner are assembled, the flange or upturned rim 7 of the lower section by contacting an inner wall of the upper section forms above the flange 6 an interior chamber 12 of comparatively large size wherein mixing of the gas andair occurs, and the formation of tar is reduced to a minimum. Moreover, when tar does collect in the chamber it can be easily cleaned out owing to accessibility to the interior thereof by simply removing the top section.

Obviously the burners can be made of any desired size and proportions, the burner herein illustrated being about three times the size of my present burner for a bicycle gaslamp. Of course the size of the burner will vary with the size of the lamp used or the size of flame desired.

.1. An acetylene-gas burner made in two removable sections, the upper section having I the gas-orifice and provided with two lbores of difierent diameters, the lower section having a gas-supply passage and being received by the larger bore of the upper section but leaving the upper part of the larger bore unoccupied to form a chamber communicating with the smaller bore and the gas-orifice.

2. An acetylene-gas burner made in two removable sections, the upper section having the gas-orifice and provided with two bores of different diameters, the lower section having a gas-supply passage and being received by the larger bore of the upper section and forming a chamber therewith, said lower section having an air-supply opening communicating with said chamber.

3. An acetylene-gas burner made in two removable sections, the upper section having the gas-orifice and provided with two bores of different diameters, the lower section having a gas-supply passage and being received by the larger bore of the upper section and means for preventing the seating of such lower section flat against the upper section, but providing a space or chamber between them, said lower section having an air-supply opening communicating with said space or chamber.

4. An acetylene-gas burner made in two removable sections, the upper section having the gas-orifice and provided with two bores of different diameters, the lower section having a gas-supply passage and being received by the larger bore of the upper section and a projection on the lower section to prevent the flat seating thereof within the upper section to form a space or chamber, said lower section having an air-supply opening communicating with said chamber, and the upper section having spring-points beyond which the lower section snaps and is held.

5. In an acetylene-gas burner made in sections providingacentral mixing-chamber and a side chamber communicating with the mixing-chamber, the upper section having the burner-tip and the lower section having the gas-supply passage and also having air-supply openings communicating with said side chamber.

6. An acetylene-gas burner made in two sections, the upper section having the gasorifice and provided with bores of different diameters, and the lower section havingagassupply passage and an air-supply passage and also having a top disk flange received by the larger bore of the upper section.

7. An acetylene-gas burner made in two sections, the upper section having the gasorifice and provided with bores of different diameters, and the lower section havingagassupply passage and an air-su pp] y passage and also having a disk received by the larger bore of the upper section and provided with an upturned flange or rim, whereby an interior chamber is formed.

8. An acetylene-gas burner made in two sections, the upper section having the gasorifice and provided with bores of different diameters and the lower section being substantially cylindrical with a central gas-passage, a disk flange on the top of the lower section and provided at its margin with an upturned flange or rim, said disk flange being received by the upper section and provided with air-supply passages.

9. An acetylene-gas burner comprising the two sections 1 and 2, the upper section 1 consisting of the two parts 3 and 4 of different diameters and having the bu rner-orifice 9 and the lower section consisting of a cylindrical portion having a central gas-passage 8 and provided with a disk flange 6 having at its margin an upturned rim or flange 7 adapted to hold the flange 6 away from contact with the upper section to form a chamber thereabove, said flange 6 having the air-holes 10.

10. An acetylene-gasburnercomprising the two sections 1 and 2, the former being of shell form to receive the latter and having the burner-orifice 9 and also having a series of indentations 11 formingspring-points,and the lower section 2 consisting of a central cylindrical portion having the central gas-passage 8, the disk flange 6 provided with air-holes 10 and upturned margin 7, the disk flange of the lower section entering the upper section and held therein by the said spring-points.

11. An acetylene-gas burner made in two sections, the upper section having the gasorifice and provided below said orifice with two bores of different diameters and the lower section provided with a central gas-passage and having a disk flange fitting the larger bore of the said upper section.
